Could be several things.
First you need to check that the SDK was compiled with the same version of
gcc (they often break the C++ ABI between versions).
Second, you also need to make sure it was compile in -mno-cygwin mode (ie.
no cygwin posix emulation layer).
You'll also need to make sure you add VLC_ADD_CXXFLAGS([asio],) in
configure.ac so the build script knows it is dealing with c++ objects
during linking. And if you don't feel like modifying configure.ac right
now, you can simply edit vlc-config and edit your plugin section like this:
